107 BTC sent to provably unspendable address, removing coins from spendable circulation
An unknown entity sent 107 Bitcoin to a provably unspendable burn address this week, destroying approximately $8.5 million in cryptocurrency value despite holding the coins for roughly 12 years through a 12,700% price increase, according to onchain data shared by Galaxy Research.
The Bitcoin, originally acquired when the asset traded near $600, was transferred to an address beginning with “11111,” a provably unspendable address with no known private keys. Bitcoin sent to such addresses remains theoretically in circulation but cannot be recovered or spent under any circumstance. The address has been previously used by Stacks for proof-of-burn transactions, including a 40 Bitcoin burn in September 2015.
Five Bitcoin addresses participated in the transfer on Monday, according to Galaxy Research’s onchain analysis shared via X. The cumulative amount sent to the burn address now totals 807 BTC, valued at approximately $59 million at press time. Unlike Ethereum or BNB, Bitcoin does not have an in-built native burn mechanism, making manual transfers to unspendable addresses the only method of destruction.
The motivation behind the burn remains unclear. Galaxy Research speculated the entity may have engaged in tax loss harvesting or destruction of illicit funds, though no definitive connection to hacks or criminal activity was established. The firm also suggested the possibility of a mistaken transfer initiated by an artificial intelligence agent.
Conor Grogan, head of product business operations at Coinbase, proposed an alternative explanation on X: “most likely an exchange that messed up their cold storage transfers.” Eric Balchunas, Bloomberg’s ETF analyst, offered multiple theories including a rogue AI agent, kidnapping, or tax-related reasons, though none has been substantiated.
The source of the Bitcoin and whether the burn was intentional or accidental remain unknown. The entity has not publicly disclosed their identity or reasoning. Cointelegraph first reported the transaction, with Zoltan Vardai writing the story and Bryan O’Shea serving as staff editor.
Bitcoin destruction through unspendable addresses is rare but not unprecedented. The practice gained visibility through Stacks’ proof-of-burn model, which uses Bitcoin burns as a mechanism for namespace registration and blockchain security. This week’s burn marks one of the largest single destructions of Bitcoin in recent years.
